Now at over two months.. I have some updates.. I havent taken pictures of tonight efforts... water too mirky after removing the skimmer and filter to apply black backing to the tank. Added some flex line to drop the skimmers pump behind the rock. Also have added some snails to my now diverse mix. I have Nassarius and Bumble Bee snails, Trochus and many Stomatella snails. I also have seen several baby turbo hitchhiker snails. Have confirmed 2 bristle worms.. one being over 2" long. But so far nothing overally negative.. here are some pics from about a week ago during my last water change.

That is my cardinal. One of two.. they were paired off for sometime..but have since with the new social setting spilt apart.. but dont seem to bother each other at all.
My black perc.. this guy has become mr. friendly in no time. Stress and this fish just dont happen.. if I go into the tank to clean, he comes up to nibble my hand within seconds.
Just a neat picture captured during a no flow moment.
